15pcs 3-45mm Diamond Coated Core Hole Saw Drill Bit for Marble Tile
A part of the review has been auto-translated.
I use these to cut through plastics vs marble or granite etc as it says it is made for... I get a better crisp non broken edge and hole than with a saw circular hole saw...well worth the buy.
Very good
Great pricing and works well as long as you do not let the cutting edge overheat. I used a light water spray when drilling glass which works well.
Great item.
